I was a Roscoe/Lakland 5ver (still am) only guy for about 10 years straight, but my wife bought me a 76 Fender P bass for my 45th birthday. I got it setup correctly and added flats and it got me hooked. Now, I only use if needed, but it got me hooked on some of the more vintage bass/sound, so I bought my 83 Fender Jazz which has its own sound. Before, I had tried pretty much all basses out there, I was endorsed by Warrior for about 13 years, but Roscoe changed all that, and then Lakland.
I recently put my Lakland 55-63 on the sale/trade block, but after playing at church, it brought back the reason I have it.
I have the same anxiety that you guys have about shipping, I had one weird one while buying on Reverb which ended in my favor, but it left a bad taste in my mouth. Once on a TB trade, the trader emailed me about something on the bass that was wrong (I forgot), but I asked him to take it to a luthier and I gave him $50 to cover a setup to be fair.
